Abstract (en)

The invention relates to an elongate material such as a wire, cable, sheath or sheet. The device according to the invention comprises two surfaces (1, 10) which are synchronously moveable and which can be moved parallel to each other over a significant length in relation to their separation in such a way as to grip between them the elongate material (11) to be driven, the said surfaces (1, 10) comprising, on their mutually opposing faces in this zone of parallel displacement, projections (6, 8) creating on the driven elongate material (11) alternate compression zones and free zones, the projections (6, 8) of at least one of the surfaces (1, 10) being elastically deformable in part. Application to the transporting of cables. <IMAGE>
